There is a warning light for the loss of plant habitats worldwide that entails concerted efforts to conserve plant biodiversity. Thus, plant species classification is of crucial importance to address this environmental challenge. In recent years, there is a considerable increase in the number of studies related to plant taxonomy. While some researchers try to improve their recognition performance using novel approaches, others concentrate on computational optimization for their framework. In addition, a few studies are diving into feature extraction to gain significantly in terms of accuracy. In this paper, we propose an effective method for the leaf recognition problem. In our proposed approach, a leaf goes through some pre-processing to extract its refined color image, vein image, xy-projection histogram, handcrafted shape, texture features, and Fourier descriptors. These attributes are then transformed into a better representation by neural network-based encoders before a support vector machine (SVM) model is utilized to classify different leaves. Overall, our approach performs a state-of-the-art result on the Flavia leaf dataset, achieving the accuracy of 99.58\% on test sets under random 10-fold cross-validation and bypassing the previous methods. We also release our codes (Scripts are available at https://github.com/dinhvietcuong1996/LeafRecognition) for contributing to the research community in the leaf classification problem., Comment: 20 pages; 9 figures; 5 tables

In the lorentzian product $\Bbb G^n\times\Bbb R_1,$ we give a comparison between the $f$-volume of an entire $f$-maximal graph and the $f$-volume of the hyperbolic $H_r^+$ under the assumption that the gradient of the function defining the graph is bounded away from 1. As a consequence, we obtain a Bernstein type theorem for $f$-maximal graphs in $\Bbb G^n\times\Bbb R_1.$ Without the condition on the gradient of the function, an example of non-planar entire $f$-maximal graph in the Lorentzian product $\Bbb G^n\times\Bbb R_1$ is given. This example shows that the assumption on the gradient of the function defining the graph in the volume comparison as well as in the Bernstein type theorem is essential.

Background: Rice bran oil is produced from rice bran, which contains nutrients such as oryzanol, lecithin, tocopherols and tocotrienol. The potential rice varieties for rice bran oil or brown rice production are the Ja23 and Ja35 lines developed by the Vietnam National of Agricultural. Using nitrogen with different levels of doses has been shown to increase photosynthesis, dry matter accumulation and seed yield in rice plants. Therefore, this study was conducted to evaluate the effects of nitrogen fertilization on grain yield, bran/rice ratio and the quality of bran, such as lipid and γ-oryzanol content. Methods: The experiment was conducted during 2021-2022 inside a net house. The experiment was arranged in a completely randomized design (RCD) with five replications for three nitrogen levels and two rice varieties. The rice grains from each cluster were milled to collect bran samples for yield, embryo, aleurone, lipid and γ-oryzanol content analysis. Result: The rice bran ratio and quality (lipid and γ-oryzanol content) of the Ja35 variety were higher than those of the Ja23 variety at all fertilizer levels. Increasing the nitrogen fertilizer did not increase the rice bran ratio but improved the quality of the rice bran. Therefore, increasing the nitrogen fertilizer level is necessary to increase the rice bran ratio and quality of the rice bran for rice varieties with larger aleurone. [ABSTRACT FROM AUTHOR]

19. A Mechanical Beam Resonator Engineered at Nanoscale for Ultralow Thermoelastic Damping
- Author

Vy, N. D., Cuong, N. V., and Hoang, C. M.
- Abstract
ABSTRACTA mechanical beam resonator engineered at nanoscale for suppressing thermoelastic damping to obtain ultrahigh quality factor is reported. The resonator employs the torsion mode of a spring beam to excite the rotation oscillation of a nanoscale resonant beam. The ultralow thermoelastic damping in the resonator is obtained by employing torsion oscillation. Optimal study of thermoelastic damping is carried out by varying the dimensional parameters of the resonator. The resonator operating in the MHz regime with the quality factor over one million is obtainable by the proposed oscillation exciting method and appropriate design of dimensional parameters of the beams. In order to obtain such overall intrinsic quality factor, virtual supports are employed to eliminate attachment loss in the resonator.

At the ALTO project of IPN Orsay, as at many others using the ISOL technique for production of intense and pure radioactive beam (RIB), it is crucial, when short-lived isotopes are produced in thick targets, to realize target and ion-source systems with good release properties and high efficiency. Therefore, R & D studies on target and ion source are very important for optimization of the production, selectivity and release of the isotopes of interest. These studies are also needed towards the future SPIRAL-2 and EURISOL nuclear physics facilities. The present work is dedicated to the production of neutron-rich gallium isotopes by the ISOL thick-target technique using photo-fission and a surface ion source. We aim at the study of the structure 82,83,84Ge50,51,52 via the -decay of 82,83,84Ga51,52,53. By this purpose, we focus on the development of a new surface ion-source made from high working function like Rh and Ir. The code written by C++ has been built to simulate the ionization efficiency of different surface ion-source (different materials and dimensions), the result of which was compared with experimental data from CERN. The code can be used to optimize ion source dimensions in future designs. Also, we have performed a test experiment to measure the ionization efficiency of the Rh and Ir-coated Rh for gallium. On the other hand, for future nuclear structure studies of refractory elements such as cobalt or nickel (atomic number Z=27 and 28 respectively), of which it is expected that they may reveal much interesting structure information, the ISOL technique with a thick target is no longer suitable. Indeed, the high melting point of these elements makes it difficult to volatilize as well as release them from a thick target. For such a situation, a technique based on thin targets is needed and the laser ion guide based on a gas cell to thermalize, neutralize and stop the recoiling nuclear reaction products combined with a laser beam to re-ionize them selectively, seems a good choice. However, in order to know whether the technique is fit for ALTO, we need to answer the question as to what the ionization rate is of the buffer gas by the primary electron beam and secondary charges? In other words, what is the ion-electron pair production rate in the gas cell? This is most important since the ionization rate negatively affects the extraction efficiency of the laser ion guide whenever it becomes bigger than 1010. To answer this question, we built a code based on the Geant-4 toolkit to simulate the ionization of the buffer gas. Furthermore, in a move towards the SPIRAL-2 project at GANIL where fission of 238U will be induced by neutrons produced in a carbon converter from a deuteron beam, we also wrote a Geant-4 code to simulate the production of neutrons, the neutron-induced fission and the energy deposit in a gas cell of similar dimensions as the proposed gas cell for ALTO. We likewise performed a simulation for the gas cell at Leuven to compare with published results., Pour le projet ALTO à l'IPN d'Orsay, comme pour d'autres laboratoires qui exploitent la technique ISOL pour produire des faisceaux radioactifs intenses et purs, il est crucial, lorsque des isotopes de courte durée de vie sont produits dans des cibles épaisses, de réaliser des cibles et des sources d'ions avec des bonnes propriétés de sortie et de haute efficacité. Ainsi les études de R&D sur les cibles et les sources d'ions sont très importantes pour l'optimisation de la production, la sélectivité et la sortie des isotopes d'intérêt. Ces études sont aussi nécessaires vers les futurs installations transnationales de recherche en physique nucléaire SPIRAL-2 et EURISOL. Le travail présent est consacré à la production d'isotopes de gallium riches en neutrons par la technique de cible épaisse ISOL reposant sur la photo-fission et l'ionisation de surface. Nous visons à l'étude de la structure nucléaire du 82,83,84Ge grâce à la désintegration bêta du 82,83,84Ga. Dans ce but, nous nous concentrons sur le développement d'une nouvelle source d'ionisation de surface faite de matériaux à haute fonction de travail comme le Re et l'Ir. Un code C++ a été construit pour simuler l'efficacité d'ionisation de la source pour des surfaces différentes (des matériaux différents et des dimensions différentes) et le résultat a été comparé avec une base de données expérimentales du CERN. Le code peut être utilisé pour optimiser les dimensions de la source d'ions dans des agencements futurs. En même temps nous avons réalisé une expérience d'essai afin de mesurer l'efficacité d'ionisation du gallium dans des cavités de Re et Ir-Re. D'autre part, pour les études de structure nucléaire d'éléments réfractaires, comme le cobalt ou le nickel, pour lesquels on s'attend à ce qu'ils révèlent un trésor d'informations de structure intéressantes, la technique ISOL à cible épaisse n'est plus appropriée. En effet, le point de fusion élevé de ces éléments fait qu'ils se volatilisent et se libèrent difficilement d'une cible épaisse. Alors une technique basée sur des cibles minces s'avère nécessaire et le guide d'ions à laser, basé sur une cellule à gaz pour thermaliser, neutraliser et arrêter les produits de réaction reculants suivie d'une ionisation résonnante laser pour les re-ioniser sélectivement, semble un bon choix. Cependant, afin de déterminer si la technique convient pour ALTO, nous devons répondre à la question quant au taux d'ionisation du gaz tampon par le faisceau primaire ainsi que les charges secondaires? Autrement dit, quel est le taux de production de paires ion-électron dans la cellule à gaz? En effet, un taux d'ionisation trop grand empêche l'extraction efficace des ions d'intérêt du guide d'ions à laser. Pour répondre à cette question, nous avons construit un code basé sur Geant-4 pour simuler l'ionisation du gaz tampon. En outre, dans un mouvement vers le projet SPIRAL-2 au GANIL, où la fission de l'238U sera induite par des neutrons produits dans un convertisseur carbonique depuis un faisceau de deutons, nous avons écrit un code Geant-4 pour simuler la production de neutrons, la fission induite par neutron et le dépôt d'énergie dans une cellule à gaz de dimensions semblables à la cellule proposée pour ALTO.

Resonant scattering with low-energy radioactive nuclear beams of E < 5 MeV/u have been studied at CRIB of CNS and at RIPS of RIKEN. As an extension to the present experimental technique, we will install an advanced polarized proton target for resonant scattering experiments. A Monte-Carlo simulation was performed to study the feasibility of future experiments with the polarized target. In the Monte-Carlo simulation, excitation functions and analyzing powers were calculated using a newly developed R-matrix calculation code. A project of a small-scale radioactive beam facility at Kyushu University is also briefly described. [ABSTRACT FROM AUTHOR]

30. Retention of functional polymers in liquid adsorption chromatography: Effect of the end groups in PEGs and their methyl ethers in different mobile phases

Cuong, Nguyen V. and Trathnigg, Bernd
- Abstract
It is shown that the end group parameter, which describes the influence of the end group on retention, can be determined in RP chromatography from two chromatograms of a nonfunctional and a monofunctional sample, if a sufficient number of peaks with the same number of repeat units in each sample can be reasonably resolved and identified. The same procedure can also be applied for pairs of di‐ and monofunctional polymers. End group parameters have been determined in three different mobile phases: acetonitrile–water, acetone–water and methanol–water of different compositions. The temperature dependence of the interaction parameter of the repeat unit and the end group parameter has been found to be different, which allows a fine‐tuning of retention.

31. Adsorption interaction parameter of polyethers in ternary mobile phases: The critical adsorption line

Cuong, Nguyen V. and Trathnigg, Bernd
- Abstract
It is shown that in LC of polymers, the interaction parameter in ternary mobile phases can be described by a plane, which is determined by the dependencies in binary mobile phases. Instead of a critical adsorption point, critical conditions are observed along a straight line of composition between the two critical points in binary mobile phases. Consequently, a separation of block copolymers under critical conditions for one block by an adsorption mechanism for the other block can be achieved in ternary mobile phases of different compositions, which allows an adjustment of the retention of the adsorbing block.

Thuy, N. T. D., Melchinger-Wild, E., Kuss, A. W., Cuong, N. V., Bartenschlager, H., and Geldermann, H.
- Abstract
This study characterized autochthonous pig breeds of Vietnam and compared them with breeds from other regions. A total of 343 animals were considered from 5 indigenous pig breeds of Vietnam (Muong Khuong, Co, Meo, Tap Na, and Mong Cai), 2 exotic breeds kept in Vietnam (Landrace and Yorkshire), 3 European commercial breeds (German Land-race, Piétrain, and Large White), the Chinese breed Meishan, and the European Wild Boar. Each individual was genotyped for 20 selected polymorphic microsatellite loci. The Vietnamese autochthonous breeds showed higher degrees of polymorphism, allelic diversity, and heterozygosity than the other pig breeds. Also, large genetic diversity was observed across the area of distribution, with village-specific subpopulations, which led to significant inbreeding coefficients. As expected, genetic distances showed large differences among European-based, Chinese, and Vietnamese indigenous breeds and reflected the geographical distribution of breeds. In comparison with the European breeds, the Vietnamese indigenous pig breeds harbored a considerable amount of genetic diversity and, therefore, will be of significance for livestock bioconservation.

- Abstract
GaN/AlxGa1–xN distributed Bragg reflectors (DBRs) for the near-ultraviolet region have been grown on sapphire substrates by metal-organic chemical vapor deposition. In order to suppress the generation of cracks and V-shaped defects on the surface of the DBRs, AlGaN/AlN superlattices and step-graded multiple AlGaN layers were inserted prior to or during the growth of the DBRs. By optimizing those layers, the reflectivity of a 40-pair GaN/Al0.35Ga0.65N DBR was increased up to 96% without any cracks and V-shaped defects. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Black and non-White Latinx children have historically been diagnosed with autism at a later age and with more significant impairments than White peers. This study aimed to gather insights from members of the autism service provider workforce on current barriers and facilitators to achieving equity in early childhood autism evaluation, referrals, and treatment. We employed a qualitative descriptive design using semi-structured virtual focus groups with autism experts in North Carolina (N = 26). Our final sample included pediatric clinicians across disciplines, researchers, family/caregiver advocates, and policymakers/government representatives. We identified four overarching themes representing challenges to equitable autism service provision: (1) workforce composition and recruitment concerns, (2) workforce capacity and accessibility concerns, (3) workforce compensation obstacles, and (4) COVID-19 pandemic adaptations' impact. Our findings demonstrate the need for improved workforce diversity, autism-specific education, adequate compensation, and interventions to address burnout. To remediate existing barriers to equity, diversity in recruitment across training levels, cultural awareness, autism education for all pediatric providers, and partnerships with caregivers as experts must be prioritized. These investments in the autism workforce will allow its interdisciplinary professionals to better meet the needs of children and families from historically marginalized communities and achieve equitable early childhood service provision. Black and non-White Latinx children tend to receive autism diagnoses later in life and with a higher degree of impairment than White children. The purpose of this study was to learn what is currently helping as well as preventing Black and non-White Latinx children from getting access to autism evaluation and services. We held virtual interviews with 26 experts who work with autistic children and their families, including clinical providers, researchers, advocates, and policymakers/government representatives. From these interviews, we identified four themes that have an impact on equity in autism services: (1) who makes up the workforce, (2) w orkforce capacity and accessibility, (3) workforce payment structure, and (4) changes due to the COVID-19 pandemic. These findings show the need for improved workforce diversity, autism-specific education, payment structures, and additional support for workforce members to avoid burnout. To make childhood autism services more equitable, diversity in recruitment across training levels, cultural awareness, increased autism education for all pediatric providers, and partnerships with caregivers as experts must be prioritized. These investments in the autism workforce will allow professionals in the field to better meet the needs of children and families from Black and non-White Latinx communities and achieve equity in early childhood autism services.

Background and Purpose: This study was conducted in line with the request of the senior management of a hospital. The objective of the current research is to identify managerial problems through the relationship between health employees' perceptions of organizational justice, trust in the manager and the organization, and job satisfaction; develop a solution proposal over the relationships between these variables and motivation variables; and present a model proposal (BUY Model) as a result. Methods: The study sample is comprised of 673 employees. The study data were collected online using a questionnaire consisting of five scales. The data were analyzed by descriptive statistical methods, correlation analysis, and regression analysis. Results: The findings obtained from the study showed that the participants' perceptions of organizational justice, trust in the manager and the organization, job satisfaction and motivation were generally at a moderate level. The study also determined that trust in the manager and the organization had a partial mediation effect on the effect of organizational justice on job satisfaction and the variables of trust in the organization, organizational justice, and trust in the manager, respectively, and especially, the job satisfaction variable also affected motivation. Conclusion: The BUY model was developed to identify problems related to the management of healthcare human resources and solve these problems. Considering the importance of the concepts of job satisfaction and motivation in terms of employee performance, health service quality, and patient satisfaction, it is thought that the developed model will benefit managers of health institutions in increasing the job satisfaction and motivation levels of health employees.

TYPE 2 diabetes ,VERNONIA ,HYPOGLYCEMIC agents - Abstract
Type 2 diabetes mellitus (T2DM), or "insulin-independent diabetes mellitus," is a worldwide health concern. Diabetes affects roughly 415 million individuals worldwide, with 193 million undiagnosed cases. The number of people afflicted in the following decades is predicted to double. Although various synthetic medications are currently available to treat/manage T2DM, their side effects compel researchers to seek novel treatment options. Because of their affinity for biological receptors and broad bioactivity, nature has long been a source of innovative medication. V. amygdalina is one of the numerous natural productswith antidiabetic properties. Several studies have shown that the extracts have antidiabetic effects in vitro and in vivo. This review examined the antidiabetic and pharmacokinetic characteristics of phytoconstituents found in V. amygdalina. [ABSTRACT FROM AUTHOR]

Plants are natural resources providing several important bioactive compounds for human health. To discover such valuable properties, researchers need to focus on both the pharmacology and toxicity of plant materials. Preliminary toxicity assessment of plants using the Brine Shrimp Lethality Test is a convenient, simple, and effective tool. However, some environmental parameters such as light, temperature and salinity need to be optimized for our own laboratory conditions and Artemia salina cysts produced in Vietnam. The obtained results indicated that the continuous lighting regime, temperature of 30 oC and salinity of 30 ppt are the most suitable parameters for cyst hatching within 24 hours and development of nauplii after 24 hours of hatching. Based on the optimal cyst-hatching procedure, the potential toxicity of 26 extracts from 24 poisonous plant species collected in Quang Tri was determined with median lethal concentration (LC50). The results showed that 3/26 extracts were extremely toxic with LC50 = 10 µg/mL; 10/26 extracts were highly toxic with LC50 from 10 µg/mL to 100 µg/mL; 8/26 extracts were moderately toxic with LC50 from 100 µg/mL to 250 µg/mL; 4/26 extracts had low toxicity with LC50 from 250 µg/mL to 1,000 µg/mL; and 1/26 extract was not toxic with LC50 > 1,000 µg/mL. The presented data could provide scientific evidence for further pharmacological and toxicological investigations of these plant species. The optimal conditions for hatching A. salina cysts in this study will be applied in our laboratory for in vivo toxicity assessment of other plant species. [ABSTRACT FROM AUTHOR]

Background: Road Traffic injuries (RTI) are among the top ten leading causes of death in the world resulting in 1.35 million deaths every year, about 93% of which occur in low‐ and middle‐income countries (LMICs). Despite several global resolutions to reduce traffic injuries, they have continued to grow in many countries. Many high‐income countries have successfully reduced RTI by using a public health approach and implementing evidence‐based interventions. As many LMICs develop their highway infrastructure, adopting a similar scientific approach towards road safety is crucial. The evidence also needs to be evaluated to assess external validity because measures that have worked in high‐income countries may not translate equally well to other contexts. An evidence gap map for RTI is the first step towards understanding what evidence is available, from where, and the key gaps in knowledge. Objectives: The objective of this evidence gap map (EGM) is to identify existing evidence from all effectiveness studies and systematic reviews related to road safety interventions. In addition, the EGM identifies gaps in evidence where new primary studies and systematic reviews could add value. This will help direct future research and discussions based on systematic evidence towards the approaches and interventions which are most effective in the road safety sector. This could enable the generation of evidence for informing policy at global, regional or national levels. Search Methods: The EGM includes systematic reviews and impact evaluations assessing the effect of interventions for RTI reported in academic databases, organization websites, and grey literature sources. The studies were searched up to December 2019. Selection Criteria: The interventions were divided into five broad categories: (a) human factors (e.g., enforcement or road user education), (b) road design, infrastructure and traffic control, (c) legal and institutional framework, (d) post‐crash pre‐hospital care, and (e) vehicle factors (except car design for occupant protection) and protective devices. Included studies reported two primary outcomes: fatal crashes and non‐fatal injury crashes; and four intermediate outcomes: change in use of seat belts, change in use of helmets, change in speed, and change in alcohol/drug use. Studies were excluded if they did not report injury or fatality as one of the outcomes. Data Collection and Analysis: The EGM is presented in the form of a matrix with two primary dimensions: interventions (rows) and outcomes (columns). Additional dimensions are country income groups, region, quality level for systematic reviews, type of study design used (e.g., case‐control), type of road user studied (e.g., pedestrian, cyclists), age groups, and road type. The EGM is available online where the matrix of interventions and outcomes can be filtered by one or more dimensions. The webpage includes a bibliography of the selected studies and titles and abstracts available for preview. Quality appraisal for systematic reviews was conducted using a critical appraisal tool for systematic reviews, AMSTAR 2. Main Results: The EGM identified 1859 studies of which 322 were systematic reviews, 7 were protocol studies and 1530 were impact evaluations. Some studies included more than one intervention, outcome, study method, or study region. The studies were distributed among intervention categories as: human factors (n = 771), road design, infrastructure and traffic control (n = 661), legal and institutional framework (n = 424), post‐crash pre‐hospital care (n = 118) and vehicle factors and protective devices (n = 111). Fatal crashes as outcomes were reported in 1414 records and non‐fatal injury crashes in 1252 records. Among the four intermediate outcomes, speed was most commonly reported (n = 298) followed by alcohol (n = 206), use of seatbelts (n = 167), and use of helmets (n = 66). Ninety‐six percent of the studies were reported from high‐income countries (HIC), 4.5% from upper‐middle‐income countries, and only 1.4% from lower‐middle and low‐income countries. There were 25 systematic reviews of high quality, 4 of moderate quality, and 293 of low quality. Authors' Conclusions: The EGM shows that the distribution of available road safety evidence is skewed across the world. A vast majority of the literature is from HICs. In contrast, only a small fraction of the literature reports on the many LMICs that are fast expanding their road infrastructure, experiencing rapid changes in traffic patterns, and witnessing growth in road injuries. This bias in literature explains why many interventions that are of high importance in the context of LMICs remain poorly studied. Besides, many interventions that have been tested only in HICs may not work equally effectively in LMICs. Another important finding was that a large majority of systematic reviews are of low quality. The scarcity of evidence on many important interventions and lack of good quality evidence‐synthesis have significant implications for future road safety research and practice in LMICs. The EGM presented here will help identify priority areas for researchers, while directing practitioners and policy makers towards proven interventions. [ABSTRACT FROM AUTHOR]

Virtual communities of practice (VCoPs) can decrease social, structural, and professional isolation, provide opportunities for knowledge‐sharing abilities, and may improve participants' self‐reported sense of connectedness to one another and their profession. However, more research is needed to examine measurement of VCoPs effectiveness on participants. In this scoping review our research question was: What is the state of the science for VCoPs and how are these communities measured in current research specific to education and health/health education? Guided by Arksey and O'Malley's five stages for conducting a rigorous scoping review, we identified gaps in the evidence regarding the overall state of the science on measurement of VCoPs inclusive of quantitative and mixed‐methods literature describing validated VCoP measurement in both English or Spanish from January 1990 to July 2023, and within the health, education, or health education disciplines. Initial searches yielded 2350 articles. Authors independently screened papers and extracted data. The results of this scoping review (N = 13 articles) highlight the measurement of VCoPs specific to education, healthcare, health education research. We found that measures had been tested in VCoPs within health, education, health education, and professional education information technologies disciplines, with the Community of Inquiry framework being the most common theoretical foundation. The findings provide an understanding of measurement tools and impacts and outcomes of VCoP participation and we make recommendations for future VCoP measurement tool development.

Covering: 1925 to July 2023 Among the sesquiterpenoids with rich structural diversity and potential bioactivities, lindenane sesquiterpenoids (LSs) possess a characteristic cis, trans-3,5,6-carbocyclic skeleton and mainly exist as monomers and diverse oligomers in plants from the Lindera genus and Chloranthaceae family. Since the first identification of lindeneol from Lindera strychnifolia in 1925, 354 natural LSs and their oligomers with anti-inflammatory, antitumor, and anti-infective activities have been discovered. Structurally, two-thirds of LSs exist as oligomers with interesting skeletons through diverse polymeric patterns, especially Diels–Alder [4 + 2] cycloaddition. Fascinated by their diverse bioactivities and intriguing polycyclic architectures, synthetic chemists have engaged in the total synthesis of natural LSs in recent decades. In this review, the research achievements related to LSs from 1925 to July of 2023 are systematically and comprehensively summarized, focusing on the classification of their structures, chemical synthesis, and bioactivities, which will be helpful for further research on LSs and their oligomers.

Background: Mental health (MH) disorders are major causes of disability in Guatemala. Unfortunately, limited academic training and funding resources make MH care inaccessible to most people in rural Guatemala. These disparities leave many indigenous populations without care. Project ECHO™ is an educational model used globally to deliver virtual training for providers in rural/ underserved communities. The aim of this project was to implement and evaluate a Project ECHO™ program bridging MH training gaps for providers who serve rural communities in Guatemala. Methods: The Project ECHO™ curriculum was implemented through a partnership between educational and nonprofit institutions in Guatemala City and the United States. Participants were primary care physicians and nurses working in rural Guatemala as well as medical/nursing/psychology students. Evaluation of its implementation was guided by a RE-AIM framework. Reach, effectiveness, adoption, fidelity, sustainability, acceptability, feasibility, and appropriateness were evaluated using a mixed-methods approach, using a pre-post survey and semi-structured focus groups. Results: Forty unique participants attended the five sessions. Attitudes about mental health did not change quantitatively but self-efficacy improved in four of five modules. High quality fidelity scores were noted in two of five sessions. Sustainability scores across multiple domains were highly rated. Scores on instruments measuring acceptability, feasibility, and appropriateness were high. Focus groups showed two main themes: the curriculum filled a gap in education and further adaptation of the model might help improve the experience. Conclusion: Implementation of the Project ECHO™ educational model appeared to have good reach/adoption, showed improvements in self-efficacy, illuminated facilitators and barriers to sustainability, and was felt to be acceptable, feasible, and appropriate. Qualitative analysis supported these conclusions. Future directions would include ongoing evaluation and monitoring of further Project ECHO™ curricular experiences through this partnership and adaptation of this project to other learners and settings in Latin America.

Healthcare organizations struggle to provide adequate assistance because of the scarcity of resources affecting National Health Systems (NHS) worldwide. It is necessary to find strategies to make the NHS sustainable. Funding cannot always be leveraged, and new variables need to be found. It is asked: What can and should be done in single health organizations to improve the efficacy of the NHS? To answer, several CEOs of Italian hospitals were interviewed. Results suggest that there is a widespread need for improvement of organizational aspects of professionals' responsibilities, better coordination between health professionals, and in-service training. Several conclusions can be sketched by the analysis of interviews. Current possible NHS problems, as well as practical suggestions on how to improve it, are offered. Bureaucracy, slow decisional processes, and weak reward systems are seen as demons to fight. How? Reforming the regulation system, valorizing professional competencies, and placing stronger emphasis on organizations' commitment. [ABSTRACT FROM AUTHOR]
